| GOOGL S4 | +3.08% | -4.72% | Signal: Direction was right — GOOGL closed the next day at 343.41, +1.56% above the 338.13 entry, so the overnight-drift call paid. Timing: Ambiguous and the data doesn't settle it. At decision time the stock was already +1.76% on the day (~350.26, consistent with the "biggest premarket movers" headline), which suggests the news move had already happened — yet the fill came at 338.13, roughly 3.5% below the decision-time price and below the prior close of 344.20. Nothing here explains that gap (late fill, reversal into the close, or a data mismatch), and it materially changed the trade: a fill near the decision price would have produced a loss. Exit: The scheduled next-close exit captured about half of the +3.08% peak and sidestepped a -4.72% trough — a wide ±4–5% swing for a one-day hold. The dominant factor is that the +1.56% result reflects where the close happened to land in an unusually wide intraday range (and an unexplained favorable fill), not a clean execution of the drift thesis. |
